香茅醇（Citronellol）是一種天然有機化合物，存在於多種植物精油以及一些水果中，屬於類萜。其兩種對映異構體在自然界中均有分佈：R-(+)-香茅醇, 存在於香茅油 (50%)；而S-(−)-香茅醇存在於薔薇屬植物精油中(18–55%)，以及天竺葵屬植物等。^[1]

製備

每年生產數百萬公斤的香茅醇。香茅醇主要由香葉醇或橙花醇在亞鉻酸銅催化劑上加氫化合成^[2]。均相催化劑用於生產對映異構體^[3]^[4]。

應用

香茅醇用於香水和驅蟲劑，^[5]農業害蟎引誘劑。^[6]香茅醇在短距離內是一種很好的驅蚊劑，但保護性能隨距離增加大大降低。^[7]與環糊精結合能增強驅蚊效用，有效時間提升至1.5小時。^[8]

香茅醇是生產玫瑰醚的原料。^[9]

健康和安全性

美國食品藥品監督管理局(FDA)將香茅醇歸入「公認安全」(GRAS)的分類，^[6]在食物中僅限作為香料用途添加。^[10]有報道稱一些人群可能對香茅醇敏感，但其作為食品添加劑時的劑量是否足以使人過敏則尚不清楚。^[11]^[12]

就皮膚安全性而言，香茅醇已被評估為一種驅蟲劑^[13] 。
